Chargers won’t use tag on Jackson this year

The San Diego Chargers say they will not use the franchise tag

this season.

The Chargers tagged wide receiver Vincent Jackson last year. But

the franchise designation would have required the team to offer the

seven-year veteran a contract at 120 percent of last year’s figure.

That would have carried a salary-cap figure of about $13.7

million.

Free agency begins March 13.

General manager A.J. Smith says the team would like to keep

Jackson ”but other teams now will enter the picture.”

The Chargers also released defensive end Luis Castillo, a 2005

first-round pick who started 79 games. He had 19 sacks and 43

tackles for loss.

Castillo injured his tibia in the 2011 opener and missed the

rest of the season.
